Whether it’s the router, network switch, network-attached storage, desktop PC, home server, or a simple smart light bulb, everything needs power, and when outages cause drops in supply, local backups need to take on the load. That’s where an uninterruptable power supply (UPS) comes in. The most common version is essentially a power strip attached to a lead acid battery, the same type of power storage used inside your vehicle. If the power goes, it automatically switches supply to ensure everything keeps running.
